Im quickly finding out that it is impossible to handle the separate pieces and position them properly. So Im guessing the proper way would be to demagnetize the pieces, glue into position and then have them remagnetized.

The question then is how to demagnetize them, I have a small demagnetizer at work to demagnetize parts coming off of the surface grinder tables, dont know if it would work on cobalts. Will have to try it tomorrow. Dealing with separate pieces of magnets is new to me so any advice is appreciated

Use one piece from each magnet, this way they should attract. Glue them, hone, then send out to be zapped.

You can also kill them using a regular ceramic zapper.

The inside edges that mate up want to repell each other making it difficult if not impossible to place both pieces in place at the same time.

Use a north on the top and a south on the bottom and vice versa on the other side.

As David said in post 2, use a positive and negative on each side, so they attract to each other.

And then send them to Alpha or Koford for rezapping.

Killing them is a bad idea.

If they are dead, they won't attract to the can, and keeping them in place will require a slug and some complicated clamping method.

OK, I just popped the other side apart and I think I see were you guys are going with this.

So then when the set-up gets rezapped everything will be right again?

Yep.

As long as it is done with a proper cobalt zapper.

It will reverse one segment on each side, and you will have a raceable setup.
